What if you've learned how to work around many of iPadOS's limitations and still think those limitations are bad?
Downloading 15 different paid or free-with-in-app-purchases or free-with-ads apps to see which one actually does what it's supposed to do is one of those workarounds. I've learned how to do it and done it a bunch of times and I don't really like it. I much prefer the macOS/Windows/Linux workflow where there's typically some established, community run and trustworthy FOSS software to do whatever conversion you need.
